Operating System Interface The os module provides dozens of functions for interacting with the operating system: >>> import os>>> os.getcwd() # Return the current working directory'C:\\Python26'>>> os.chdir('/server/accesslogs') # Change current working directory>>> os.system('mkdir today') # Run the command mkdir in the system shell0 Be sure to use the import os style instead of from os import *. This will keep os.open() from shadowing the built-in open() function which operates much differently. The built-in dir() and help() functions are useful as interactive aids for working with large modules like os: >>> import os>>> dir(os)<returns a list of all module functions>>>> help(os)<returns an extensive manual page created from the module's docstrings> For daily file and directory management tasks, the shutil module provides a higher level interface that is easier to use: >>> import shutil>>> shutil.copyfile('data.db', 'archive.db')>>> shutil.move('/build/executables', 'installdir')
Think Python. Software: Python Sidebar. When programming Python, I tend to visit the most current reference documentation quite often.
To get faster and more convenient access to the documentation, inspired by Mark Hammond’s sidebar, I wrote an updated sidebar for the Mozilla family of web browser. The sidebar also offers simple searching of related python websites and mailing lists. It might be semi-useful in other browsers as well, but the main target here is Mozilla.
